Stay cool and protect your head—a reflective barrier in these hard hats lowers the temperature by 20 degrees. A full brim runs around the hat to shield your head and neck from sun, rain, and glare. It offers 12% more coverage than the brim on a standard full brim hat, providing additional protection from the elements. A built-in sweatband keeps perspiration out of your eyes, even if you sweat.

Type I hard hats protect against blows to the top of the head only. A foam shell absorbs impact, reducing force on the neck and head. To fit the hard hat snugly to your head, turn a knob on the back that tightens the suspension. The reversible suspension lets you turn the hat around without taking it off. For example, spin the hat to move a face shield out of the way or turn the hat to fit in a tight space. You can also add attachments such as face shields or earmuffs to the mounting slots on the hat.

Class C hard hats have not been tested for electrical protection. Class E hard hats insulate from electrical shocks and are often used near overhead power lines and high-voltage equipment. They’re tested at 20,000 volts.

Hard hats with ventilation holes add another way to stay cool by letting air circulate.

Soak up sweat and keep hair from getting caught in equipment. These liners are also used to compress long hair so that hard hats fit more securely. All are machine washable.

Liners for head coverage have an elastic band for a snug fit. Soak them before wearing them, and they’ll cool you off as the water evaporates. With UPF 50 sun protection, they’ll also shield your skin from harmful UV rays.

Liners for head and nape coverage have tails that extend past the hard hat, covering your neck. A sweatband in the front helps keep moisture out of your eyes.

With a low profile, these hard hats give close-fitting protection to your head in confined spaces. They don’t have a brim, so you can see what’s above you and avoid snagging on climbing gear. Chin straps hold these hard hats in place when working in strong wind, upside down, and sideways. For protection from more than just falling objects, these hard hats are rated ANSI/ISEA Z89.1, Type II to deflect both top and off-center blows to the head. Made of ABS plastic, they resist impacts better than standard hard hats. A foam shell reduces the force on the head and neck during impact by absorbing the force.

A sweatband keeps perspiration out of your eyes, and the padding has high-purity silver embedded in it to resist odor. To add a face shield, earmuffs, and other accessories, use the mounting slots on the sides.

Class C hard hats have not been tested for electrical protection. They have ventilation holes that increase air flow to keep you cool.

Hard hats with MIPS (multi-directional impact protection system) provide more protection to your brain than standard climbing-style hard hats. A low-friction layer inside the helmet allows your head to shift slightly during an impact. This shift directs rotational force away from the brain, so it causes less damage. These hard hats also have clamps for headlamp straps.

Hard hats with brim grip can be securely grasped by the back while wearing gloves. These hard hats also have a magnetic clasp, so you can connect and release the straps with one hand.

Spot sun damage that weakens your hard hat so you know when it’s time to replace it. These hard hats make the invisible damage visible with a red patch that gradually changes to white the longer it’s exposed to UV rays. Rated Type I, these hard hats protect against blows from falling objects to the top of the head. They have mounting slots for attachments such as face shields and earmuffs. To adjust the fit, turn the ratchet in the back. These hard hats have a sweatband to keep perspiration out of your eyes.

Class C hard hats have not been tested for electrical protection. Hard hats with a full brim keep rain and sun off your face, neck, and the sides of your head.

Hard hats with reversible suspension let you swing the brim to the back of your head without taking them off or adjusting the suspension.

Hard hats with ventilation holes have slots that increase air circulation to keep you cool.

These hard hats give all-in-one head, face, and ear protection. You can lift the face shield and earmuffs when not in use. Turn the ratchet in the back to adjust for a secure fit.

Type II, Class C hard hats protect your head from blows to the top and the sides. A foam shell absorbs impact to reduce force on your neck and head. These hard hats have chin straps, so they stay secure when working sideways, upside down, and in the wind. Designed for forestry, they have a corrosion-resistant steel mesh lens that guards the face while letting a cool wind in. They also have ventilation holes to increase air circulation and maintain a comfortable temperature. Their ratchet knob pivots to fit around ponytails and bandanas. They have not been tested for electrical protection.

Convert a hat into a bump cap to protect your head from minor bumps and scrapes. The insert tucks inside your hat's sweatband for secure positioning. Ventilation holes increase air circulation to keep you cool. Foam padding on the inside of the insert increases protection and comfort for your head. All are adjustable to fit your head size.

Extra-venting inserts have more venting holes than standard inserts for greater breathability, so they're often worn outdoors or in hot conditions.

Hinged inserts have a flap in the back to let long hair escape and lay flat for a non-bulky fit.

Cut-to-size inserts can be trimmed with scissors for a fully customized fit.

Often used in search and rescue operations, these helmets have rail mounts for night vision goggles, headsets, and other equipment. With devices secure and hands free, you can focus on your mission. Their polystyrene liner protects the neck and head by absorbing force during impact. To hold the helmet secure on your head, a ratchet in the back adjusts the fit. Chin straps keep the helmet in place when working upside down and in heavy wind. These helmets meet U.S. safety standards for military operations and European safety standards for whitewater sports and mountaineering, protecting your head in a variety of extreme environments.

To keep you cool under pressure, the helmets have ventilation holes and moisture-wicking padding. Snap the included vent covers on when you need to keep dust and debris out. They also have a sweatband to prevent perspiration from getting in your eyes.

Use a headlamp adapter (sold separately) to attach a light to the night vision goggle mount without needing to use tools. The adapter holds the lamp firmly to the helmet so it doesn't slide off during use.

Use headset adapters or headset and boom microphone adapters (both sold separately) to clip communication systems onto the helmet. Once the adapters are installed, you can take the communication systems on and off without tools. Headset adapters are compatible with helmet-mounted headsets. Headset and boom microphone adapters let you convert headsets with a headband or neckband to helmet mount. Once attached, the headset earpieces can be flipped up when you’re not using them so it’s easier to take the helmet off quickly. They also include a boom microphone adapter.

Add a visor (sold separately) to the helmet for eye protection. No need for tools—just snap it on. Once attached, you can lift the visor away from the face and lock it in the up position. A coating on the inside and outside resists scratching. These visors are rated EN 166:2002 Class 2B for clarity and impact resistance to protect from debris, water, and wind.
